The opinions and information provided in this report have been provided in good faith and on the basis that every endeavour has been made to be Because poplar prefers deep soils, growth rates tend to decrease going up the slope (McIvor et al. Harvesting of Poplar and Willow Poles begins on the 1st of June and continues through July and part of August. yunnanensis). Lombardy Poplar & Willow Appletons Tree Nursery : Denomination: Poplar: Clone Name: Dudley: Scientific Name: P. deltoides x P.nigra: Description: Male upright tree with only a few heavy limbs. The main species used are Salix For instance, planting hybrid poplar trees near houses is not recommended. Trees are planted at The fall foliage is a yellow color, but these trees are not primarily grown for their autumn display value. 2011). Other early introductions included S. willow poles. Although boron penetration has been found to be satisfactory for protection against insect attack in protected interior situations (Wilkinson, 2000), protection to the H1.2 hazard class required for structural applications would require demonstration of durability performance equivalent to H1.2 treated radiata (T. Singh, pers. Wilkinson (2000) recommended a stocking of 100 stems/ha for agroforestry in order to balance timber production with pastoral production. 2011). Poplar has good strength properties in relation to density (Hunter and McIvor, 2008; McIvor, 2010). This is a balsam poplar, originally selected in Belgium, and released in New Zealand in 1979. matsudana and its alba hybrid, and black poplar Pollarding Willows from Within the Tree - Duration: 5:18. Wide spacing between trees does not cause significant shading of pasture (McIvor et al. comm). The poplar was planted in the 1870s and is one of the oldest and largest of its kind in the country. Creative Commons Attribution-NonCommercial 3.0 New Zealand Licence. However, this method is suitable only for establishing poplar in the presence of stock rather than establishment of high tree stockings. Solutions. Poplar and willows are widely planted in pastoral hill country for erosion control. Poplar trees thrive in warm weather and moist to wet soil. 2011). Poplar and willow ambassadors launched around New Zealand Posted on October 01, 2020 A group of top farmers have joined forces with the Poplar and Willow Research Trust to help promote the value of poplars and willows on New Zealand farms. market gardens. Although this is lower than for radiata pine, there remains potential for selecting higher density clones for sawn timber production (Wilkinson, 2000). They have white bark, a straight trunk and t… Some poplar cultivars have been evaluated in New Zealand for wood density, sawing, machining and drying properties (Wilkinson, 2000). on old trees.12 It became naturalised in NZ in 198313. Although not suitable for very exposed situations, it is promising for horticultural shelter because it retains a very good low branch structure and autumn leaf fall is not until mid-June. Some poplar cultivars such as black poplar hybrids cope with some wind exposure, while balsam poplar hybrids offer improved possum resistance but where exposed to wind have poor form (Wilkinson, 2000). utility timber, although the poplar market in New Zealand is small and fragmented. If large areas of erodible hill country are to remain in pastoral production in New Zealand, there is potential for poplar agroforestry to create "a large, economic resource of pruned poplar sawlogs", an industry with "contrasting fibre and wood characteristics to those of pine" suitable for integration with pastoral farming as a viable crop that complements the radiata resource (Wilkinson, 2000). POPLAR PARTNERSHIP LIMITED was incorporated on 02 May 2002. were among the early introductions. Knowles (2006) suggested that "the low stockings often employed for poplar pole planting may make them less effective for erosion control than commonly thought", while a 1992 study showed that mature spaced trees, where well maintained, "reduced soil erosion by about 60% to 70%, while poorly maintained poplar plantings had minimal effect." There is an export market for the logs, which may attract a slight premium over radiata pine (Hunter and McIvor, 2008) and "there is a small but growing market for poplar timber." Female trees shed white fluff in the spring, hence the name. Branches readily break off This is a balsam poplar, originally selected in Belgium, and released in New Zealand in 1979. The bark turns black and develops furrows as the tree ages. 2011). Rooted cuttings may play an increasingly important role in woodlot establishment, especially in drier sites (Wilkinson, 2000) where deep planting is required for trees to access permanent soil moisture and establish successfully (Hunter and McIvor, 2008). Surface coatings are easily applied and poplar takes an even stain (Wilkinson, 2000). These large trees have a gnarled open form, rough bark and large, tear-shaped leaves that turn yellow in the fall. Poplars were first grown in New Zealand in the 1830s. Poplars can grow very tall and anchor their trunks with powerful roots. Leaves are dark green on top and light green below with red veins and a straight base. are easily grown from stem cuttings. seen from a distance. Poplar is a fast growing tree, but site adaptability for the range of poplar cultivars grown in New Zealand is not yet fully understood (Wilkinson, 2000). Tension wood is present which may cause wooliness and collapse in sawn boards (Williams et al., 1986). Within-cultivar density varies little between region, site and position in the tree (Wilkinson, 2000), suggesting that very even strength properties can be expected, possibly an advantage when characterising strength properties for use in structural products. 1986). Easy Big Trees is the largest tree and shrub supplier on the South Island, with over 90,000 plants in stock on 30 acres in Southland. poplar (Populus nigra ‘Italica’), eastern cottonwood This research Branching is upright and leaves are green and oval, forming a point, and turning yellow in the winter. 2011). symbolise his life taking a new pathway – away from war and To qualify, landowners need to have a Farm Environment Plan (or planting plan) and commit to maintaining the trees so they can do the job they’ve been planted to … Pruning for timber requires an initial form prune before year two and for clearwood requires interventions from year two to four, with lifts every two years until the lifts reach between six and eight metres (Hunter and McIvor, 2008), best achieved by retaining 50% of the height of the tree as green crown (Wilkinson, 2000). comm). Pressure treatment of dry sawn timber with CCA salts has been shown to provide variable penetration (Williams et al. The poplars that now grace erosion-prone However, eighteen years after Wilkinson published his vision, the question still remains whether sufficient research has supported a future role for poplar whereby "high value products can be identified and grown". The trees are part of a stand of poplars that were planted in the late 1920s along the Avon River, between Madras and Manchester Sts. crack willow was the main species used for nearly 100 years. CARPINUS BETULUS - Hornbeam. Lombardy poplar (Populus nigra ‘Italica’), eastern cottonwood (P. deltoides) and silver poplar (P. alba) were among the early introductions. wide spacings (25–150 stems per hectare), so pasture can 1986). Its growth rate is reasonably rapid, and it is highly resistant to both poplar rusts and to Marssonina . How to care for Poplar and Willow poles 11 ET: LM: CT 11 October 2006 Video Available A video on planting and looking after poles is available from the Regional Council. Members of the Ringatū church, which he Breeding programmes thus focus on producing male cultivars (Wilkinson, 2000). accurate and not misleading and to exercise reasonable care, skill and judgement in providing such opinions and information. Desiccating winds are damaging (Van Kraayenoord and Hathaway, 1986) and trees become deformed and stunted where planted on exposed upper slopes and ridges (Wilkinson, 2000). A 150-year-old poplar tree at Frimley Park is to be halved in height amid safety concerns. The wood has an attractive lustre where clear coated (Williams et al. But I couldn’t live on chocolate all day, every day. diseased poplars. Therefore, some evidence-based research would be required before introducing poplar into the building code as an acceptable solution for structural applications. poplar species to investigate their timber potential. Remove any leaves from the lower third to half of … Cottonwoods (Populus deltoids)grow throughout much of the U.S., and especially along streams and rivers. Small and inconspicuous individual flowers occur in clusters of spikes (<17 cm long, Sept-Nov) are followed by smooth fruits (<8-10 mm diameter) made up of two sections with a groove in between, and two small 'antennae' that stick out from the top. Willow hybrids and hybrid poplars are used for Willows and poplar foliage can provide nutritional fodder When 2011). The poplar species native to North America are divided into three loose groups: the cottonwoods, the aspens, and the balsam poplars. The mahoe is an important nursery tree for most native species, plus it is known for its distinctive white bark (which is often covered in white lichen), and heavy crops of small purple berries on the female trees (if a male is nearby). I like chocolate and it makes me fat. Northland Regional Council offers a limited number of poplar poles and willow material each winter to help prevent and control erosion in Northland. StringDancer 28,778 views. The Author and NZFFA will not be responsible if information is inaccurate or not up to date, nor will we be responsible if you use or rely on the information in any way. Farming poplar for carbon also offers hill country livestock farmers an opportunity to reduce erosion risk at low cost, with the requirement being for 30% tree canopy cover, potentially fulfilled with as few as 40 space planted trees per hectare (Eyles, 2010). Poles have a ‘head start’ over seedlings and are less likely to be damaged by browsing animals. Its growth rate is reasonably rapid, and it is highly resistant to both poplar rusts and to Marssonina . NZ $0.00 . about 1880 he planted a poplar stem at Tamatea pā to Although poplar has the potential to become a serious weed species where breeding populations are established, very few populations of poplar in New Zealand are established and self-perpetuating (i.e. poplars were often planted near central North Island Māori In-grade testing of poplar has shown that working stresses were similar to medium-density radiata pine visually graded to No. However, little data is available on how effective "spaced" poplar is in controlling erosion (McIvor et al. Suitable for general soil conservation and typically used on lower slopes. 1986). 2011). recommends Lombardy Poplars. for stock during droughts. Willows were also an early import. During the latter half of the 19th century, Lombardy to be cleared to prevent flooding. These roots might cause problems for homeowners or gardeners who are not familiar with basic poplar tree facts. Poplar wood has low natural durability. NZ $0.00. 19:55. NZ $0.00. slopes. BETULA JACQUEMONTII - Himalayan Birch. Lombardy poplar trees are best known for their columnar form and unusual branching structure—the branches start close to the ground and grow upward, parallel to the trunk. Poplar is not listed for structural applications in NZS 3602:2003 Timber and Wood-based Products for Use in Building, so durability performance would need to be demonstrated before structural products could gain acceptance in the New Zealand construction market. POPLAR PARTNERSHIP LIMITED. Words: Sheryn Clothier Cows like ryegrass and it makes them fat. Poplar can be grown to 800 m altitude without frost damage (Van Kraayenoord and Hathaway, 1986). Trading for more than 100 years, our established plant nursery stocks a wide range of native trees and other varieties, delivered across New Zealand. hillsides are most likely to be hybrid clones of various At first, little attention was given to the problems that In New Zealand poplar is primarily grown for erosion control, but even so it can be managed and harvested for timber. Applications include decorative veneers, plywood, construction, furniture and wood-based composites (McIvor, 2010). increasingly used to stabilise slopes in the central North could occur as the willows grew. On good sites it grows faster than radiata pine, it can reach a marketable size in 20 years or less, and it can attract better prices than radiata pine as export logs. italica) swabian alb, baden-wuerttemberg, germany - lombardy poplar trees stock pictures, royalty-free photos & images green natural scenery - lombardy poplar trees stock pictures, royalty-free photos & images The New Zealand breeding programme has aimed for a basic wood density of at least 360 kg/m3 (Wilkinson, 2000). Disclaimer: In Dean Satchell They are fast growing on moist, fertile sites, and founded, likened the upright branches of this poplar to the Commercial re-use may be allowed on request. Fodder - An added benefit of the willow and poplar leaves is that the young branches can be pruned off and given to stock when feed is short, over the dry summer months. Root mass is proportional to tree diameter and high planting densities are required for younger poplar trees to develop a structural root network sufficient to control erosion (McIvor et al. towards peace. TreeLine has a number of different Poplar and Willow tree species available for sale. Thus, wide spaced trees would take longer to achieve high levels of soil binding than where closer planted; and where erosion potential is severe, a closed canopy tree cover is recommended (McIvor et al. Shrub or small tree (<5 m) with smooth, heart-shaped leaves (3-20 cm long) that turn red with age. 25m SKU: popyun6 Category: Trees Tags: chinese poplar , deciduous , hardy , populus , shade , shelter , specimen , sun , yunnan poplar , yunnanensis ALBIZIA JULIBRISSIN - Silk Tree. The heartwood can be difficult to distinguish from the sapwood and the wood is odourless (Wilkinson, 2000). ALNUS GLUTINOSA IMPERALIS - Cut Leaf Alder. However, studies and deployment in New Zealand to date have been limited. They were brought in as ornamental trees and for shelter. Canterbury Grown Our nursery grows millions of trees and shrubs for projects across the country. The very rapid growth rate makes it ideal for use in a shelter belt situation or as a very tall screen. Main Points Soak poles Never plant without soaking Plant as soon as possible after soaking Look after the trees when planted Prune selectively later. Poplar, (genus Populus), genus of some 35 species of trees in the willow family (Salicaceae), native to the Northern Hemisphere. All non-text content is subject to specific conditions. Large areas of New Zealand’s hill country, including much of the East coast of both islands is not suitable for stabilising with poplar and willow because of inadequate soil moisture during summer (Van Kraayenoord and Hathaway, 1986). were brought in as ornamental trees and for shelter.

America and Asia for research and breeding. alongside Napoleon’s grave on St Helena, were planted at 5:18 . 1 framing (Wilkinson, 2000), provided adjustments were made for density; and critical joints had additional fixing (Wilkinson, 2000). PDF download of this report ». This company is now Registered. Two mature poplar trees that border the Avon River near Margaret Mahy Playground are being removed due to signs of decay. comm) but two months of boron diffusion provided boron retention well above the requirements of the H1.2 specification for both 25 mm and 50 mm thick boards (Williams et al. Although the product would be inferior to and in most cases be in direct competition with radiata pine (Williams et al., 1986), structural products requiring good appearance properties such as exposed rafters, posts and beams along with laminated structural products may hold some market potential. on sandbars and banks they can soon choke the waterway. Kiln drying of poplar timber from green can be achieved in two to three days without degrade (Wilkinson, 2000). All text licensed under the Creative Commons Attribution-NonCommercial 3.0 New Zealand Licence unless otherwise stated. The arrival of the species in New Zealand is, however, not well documented. However, poplar appears to have not been tested using contemporary CCA treatment methods such as steam pre-treatment under pressure to condition green timber for treatment. The aim is to restrict the knotty core to a central diameter of 150 mm over pruned branch stubs, but epicormic shoots that follow pruning can be an issue (Wilkinson, 2000). (Hocking, 2006a). Selected poplars and willows are also used for © Crown Copyright. Between 1950 and the late 1970s soil conservation Pressure treatment of poplar with boron has provided unsatisfactory penetration results (T. Singh pers. (P. deltoides) and silver poplar (P. alba) continue growing between them. Maggy Wassilieff, 'Trees in the rural landscape - Poplars and willows', Te Ara - the Encyclopedia of New Zealand, (accessed 7 January 2021), Story by Maggy Wassilieff, published 24 Nov 2008. Willows have been extensively used for river control, and Where timber production is prioritised under an agroforestry regime, the stocking can be increased to 200 stems/ha (Wilkinson, 2000). Because of poplar's rapid growth rate, timber suitable for a range of products can be produced in relatively short rotations (McIvor, 2010). (Salix babylonica) cuttings, reputed to be from A very tall, fast growing tree that remains tight and upright in form as it grows. stream banks. There are a few willow clones that do not have brittle Poplar trees were introduced to New Zealand and are used as windbreaks in many areas, particularly the Canterbury Plains. Poplar also has potential as a plantation forestry species and as silvo-pastoral plantings in the presence of stock. Poplar requires at least moderate soil moisture (Wilkinson, 2000). ACER PALMATUM Osakazuki - Japanese Maple. This data clearly shows that site is important for volume production, which increased by a factor of 3 from a poor site to a good site. S. viminalis. Having animals without trees means you have only half an ecosystem. The light colour of the timber is appreciated by the appearance market but low surface hardness detracts from use in furniture making, despite the wood's attractive appearance (Wilkinson, 2000). It is listed as a notable tree on the New Zealand Tree Register. In the 1930s the New Zealand Forest Service imported more Fill a 5-gallon bucket three-quarters full of water. Weeping willow Island. It can be borrowed free of charge, or purchased for $11 plus postage. Although not suitable for very exposed situations, it is promising for horticultural shelter because it retains a very good low branch structure and autumn leaf fall is not until mid-June. If you want further information on any species please contact us. fast-growing shelter belts, especially around orchards and Poplar pulps have excellent papermaking qualities suitable for fine paper production (Williams et al., 1986) and pulps with "high bulk, moderate strength properties, and excellent optical properties" can be produced from poplar (Richardson and Jones as cited in Wilkinson, 2000), offering an excellent addition to a softwood base of radiata pine (Williams et al., 1986). I'm So Poplar - Duration: 19:55. This reduces to 128m3/ha for a 20 year rotation on a poor site and 161m3/ha for a 30 year rotation on a poor site (Wilkinson, 2000). Poplar wood has low to medium density, an even pale white colour, indistinct growth rings and a fine texture (Wilkinson, 2000). Pruning is best undertaken in Autumn rather than spring to minimise epicormic shoots (M. Hunter, pers. in storms and floods and float downstream. is a great reference tool as well as an online store, there’s sure to be something to get you growing! Poplar Selection and Management The main cultivars currently available in New Zealand are listed overleaf. willow growth becomes too dense in river channels, it needs 2011). Chinese/Yunnan Poplar Wide crown, large, dark-green leaves that hold late into autumn. Their business is recorded as NZ Limited Company.As so far this company has running for 18 year(s) 252 days. In their deciduous state poplar can tolerate heavy frosts, but some cultivars may suffer frost damage to the growing shoot caused by late spring and summer frosts. Poplars are not happy on exposed eroding hillsides (Knowles, 2006), preferring alluvial terraces and moist valley bottoms (Wilkinson, 2000). ACER RUBRUM Columnare - Red or Canadian Maple. Those with a relatively high basic wood density are the most likely to produce acceptable sawn timber, providing trees are correctly tended. Although conservation poplar plantings do not ensure erosion will be prevented, with spaced plantings of poplar, production losses attributable to landslides could potentially be significantly reduced once the trees reach diameters greater than 30cm (McIvor et al. columnar poplar avenue, pyramid poplar, pyramid poplar (populus nigra var. opulus Aspens (Populus tremuloides)grow at high altitude in the Rocky Mountains and a few other areas in the U.S. Resistant strains, selected from plants held at parentages or the Chinese poplar (P We can deliver to most areas in the North Island. Greenish-white flowers appear in November-December, and then the fruit from January-March. If they take root The necklace poplar is generally thought to have originated in France in the 1770's as a (female) sport from cuttings planted from Populus deltoides, the American cottonwood.

They grow most prolifically in the southern states where these conditions are met. stock proved invaluable in the mid-1970s, when two virulent The contrast between the Leylandii Pinesand Poplars complement each other. poplar rusts devastated mature stands of poplar throughout Poplar root systems exhibit strong extensive growth and bind soil effectively, with root grafting between adjacent trees (McIvor et al. column-like form, was especially favoured – it was often Poplar only grows in low rainfall areas where the water table is high (Wilkinson, 2000), so on hillsides in summer-dry regions, planting should be restricted to channels, tunnel gullies and seepage areas (Wilkinson, 2000). These trees thrive in moist areas and additionally; their bright yellow Autumn foliage is very attractive. They We are able to design systems to retain slips. Lombardy poplar, with its naturalised), likely because the widely distributed clones are either unisexual or non-breeding hybrids, limiting spread by seed (Wilkinson, 2000). Sustainable Forest Solutions Trees provide shelter, food, and medicine, capture and recycle waste, and provide habitat for beneficial companions. Poplars Poplars were first grown in New Zealand in the 1830s. High quality pruned logs have excellent potential for sliced and peeled veneer (Williams et al., 1986). In order to produce knot-free timber pruning is essential (Wilkinson, 2000). planted to mark boundaries and river fords as it could be Poplar is a fast growing tree, but site adaptability for the range of poplar cultivars grown in New Zealand is not yet fully understood (Wilkinson, 2000). scientists imported about 200 poplar varieties from Europe, Nevertheless, CCA preservative treatment of roundwood was found to be satisfactory (Williams et al. NZ $0.00. Queenstown's famed poplar trees have crushed cars, damaged a motel and killed a man, but the council still won't test the internal rot of the tree trunks. Because they seed and germinate well in New Zealand conditions and they grow rapidly they can become a pest when they grow in the 'wrong' place. In the absence of stock, high stockings are achieved by using small stakes or forestry "wands" (Wilkinson, 2000). Poplars prefer and grow best in fertile, moist and friable soils (Van Kraayenoord and Hathaway, 1986; Hunter and McIvor, 2008). The Forest Research Institute modelled growth rates for pruned trees and found that on good sites poplar can produce over 400m3/ha volume production at 200 stems/ha on a 20 year rotation and over 500m3/ha on a 30 year rotation. the country. Akaroa in 1839. 1986) but sawn timber recoveries are lower than for radiata pine, with the main timber defect being knots (Wilkinson, 2000). Poplar saws easily (Williams et al. Machining properties are inferior to radiata pine (Wilkinson, 2000). Globally, emerging applications for poplar include engineered wood composites, chemical extracts and bio-energy (McIvor, 2011). river control work, as well as for soil conservation on hill Poplars for the Farm Specially bred clones for New Zealand conditions Poplars grow quickly and are effective for soil conservation, stock shelter, shade, fodder and they are used as ornamental trees in cities and rural settings and make a good source of timber. These are trees your stock can benefit from. Specialised markets exist in Asia, where poplar is an accepted timber species (Wilkinson, 2000). NZ $0.00. They are suitable for shelter belts, soil conservation and bio-engineering and a range of other applications. fragilis, S.alba, S. cinerea and the Soil Conservation Centre in Aokautere, near Palmerston
